WHEELED SCRAPER.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed December 4, 1906. Serial No. 346,284.

To all whom it may concern:

Be it known that 1, JOHN SMITH NORRIS, a citizen of the United States, residing at Red Lodge, in the county of Carbon and State of Montana, have invented certain new and useful Im rovements in Wheeled Scrapers, of which t e following is a specification.

My invention relates to devices used for loading and transporting dirt in excavating, grading, &c., and has for its object the improvement of the wheeled scoop-scrapers usually employed in this class of work, to the end that the dirt is more easily loaded into the scraper and more easily carried when so loaded, the weight of the loaded scoop being carried by three wheels, instead of by two, as in the scrapers generally employed, thus preventing the device from swinging and the tongue of the vehicle from striking the draft animals. I

The construction and operation of my invention will be explained in detail hereinafter and illustrated in the accompanying drawings, in which Figure 1 is a side view of my improved wheeled scraper; Fig. 2, a rear view; Fig. 3, a top plan view, and Fig. 4 a detail view of the scoop.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

1 indicates an inverted-U-shaped frame, having open rectangular frames 2 at each side thereof, with stud-shafts 3 extending from each side thereof, on which are journaled wheels 4. 5 indicates the draft-pole, secured to the top of frame 1, and 6 braces secured to the draft-pole 5 and rectangular frames 2. 6 indicates rectangular frames swivelly secured to the tops and bottoms of frames 2, in which are fulcrumed levers 7. The scoop 8 has its front end made lower than its rear portion and wider, as shown at 9, so as to more quickly fill the scoop when loading. The front ends of levers 7 are pivotally secured to cars 10 on the front end portion 9 of the scoop 8, and as the rear ends of the levers extend to the rear of the machine it will be understood that the action of the scoop in loading may be easily controlled by the operator.

11 indicates ears secured on the sides of the scoop 8 and 12 hooks secured to the levers 7 to engage said ears when it is desired to raise the rear portion of the scoop. 13 indicates lugs or projections on the rear of the scoop to rest on a cross-bar 14, having forward extensions 15 with downwardly-exthe scoop is loaded, the hooks 12 still engaging ears 11, the rear of the scoop is lowered, so that lugs or projections 13 rest on crossbar 14, and the rear ends of the levers 7 depressed, so as to raise the front of the scoop.

WVhen it is desired to dump the scoop, the hooks 12 are caught in ears 11 and the rear ends of the levers 7 raised, so as to sink the front edge of the scoop in the ground. The hooks 12 are then disengaged from cars 11, and the machine being drawn forward the scoop is overturned, swinging on the front ends of levers 7. To right the scoop, the front end is lifted by depressing the rear ends of levers 7 and the scoop thrown over.

Having thus described my invention, What I claim is 1. In a wheeled scraper, an upright frame .having Wheels journaled at its ends, a crossbar secured to said frame, a trailer-wheel swivelly secured to said cross-bar, levers fulcrumed on said upright frame, and a scoop pivotally secured to said levers and supported by the cross-bar, substantially as shown and described.

2. In a wheeled scraper, a wheeled frame, levers fulcrumed on said frame, a scoop having its front end pivotally secured to said levers and its rear end supported by said frame, ears on the sides of said scoop, and hooks on said levers to engage said ears to manipulate the front end of the scoop, substantially as shown and described.

3. In a wheeled scraper, a wheeled frame, levers fulcrumed on said frame, a scoop having its front end pivotally secured to the front ends of said levers, lugs on the rear end of said scoop to engage the frame, ears on the sides of the scoop, and hooks on said levers to engage said ears, substantially as shown and described.

4. In a wheeled scraper, an inverted-U- IIO shaped frame, rectangular frames at each side thereof, wheels journaled on said rectangular frames, other rectangular frames swivelly secured in the first-mentioned rectangular frames, levers fulcrumed in said swiveled frames, a scoop having its front endpivotally secured to the front ends of said levers, ears on the sides ofsaid scoop, and hooks on said levers to engage said ears, substantially as shown and described.

"5, In a wheeled scraper, an inverted-U shaped frame, a rectangular frame at each side of said invertedU-shaped frame, wheels journaled on said rectangular frames, a crossbar secured to said inverted-U-shaped frame, a trailer-wheel swivelly secured to said crossbar, other rectangular frames swivelly mounted in the first-named rectangular frames, levers fulcrumed in said swiveled frames, a scoop having its front end pivotally secured to the front ends of said levers, lugs on the rear end of the scoop to engage the cross-bar aforesaid, ears on the sides of the scoop, and hooks on the levers to engage said ears, substantially as shown and described.

In testimonyv whereof I hereto affiX my signature in the presenceof two witnesses. JOHN SMITH NORRIS. Witnesses:
